  Educators are seriously concerned about the high rate of dropouts among the doctor of philosophy candidates and the consequent loss of talent to a nation in need of Ph. D. s. Some have placed the dropouts loss as high as 50 percent. The extent of the loss was, however, largely a matter of expert guessing. Last week a well-rounded study was published. It was published. It was based on 22,000 questionnaires sent to former graduate students who were enrolled in 24 universities and it seemed to show many past fears to be groundless.
The dropouts rate was found to be 31 per cent, and in most cases the dropouts, while not completing the Ph. D. requirement, went on to productive work. They are not only doing well financially, but, according to the report, are not far below the income levels of those who went on to complete their doctorates.
Discussing the study last week, Dr. Tucker said the project was initiated ‘because of the concern frequently expressed by graduate faculties and administrators that some of the individuals who dropped out of Ph. D. programs were capable of competing the requirement for the degree. Attrition at the Ph. D. level is also thought to be a waste of precious faculty time and a drain on university resources already being used to capacity. Some people expressed the opinion that the shortage of highly trained specialists and college teachers could be reduced by persuading the dropouts to return to graduate schools to complete the Ph. D.’
“The results of our research” Dr. Tucker concluded, “did not support these opinions.”
Lack of motivation was the principal reason for dropping out.
Most dropouts went as far in their doctoral program as was consistent with their levels of ability or their specialities.
Most dropouts are now engaged in work consistent with their education and motivation.
Nearly 75 per cent of the dropouts said there was no academic reason for their decision, but those who mentioned academic reason cited failure to pass the qualifying examination, uncompleted research and failure to pass language exams. Among the single most important personal reasons identified by dropouts for non-completion of their Ph. D. program, lack of finances was marked by 19 per cent.
As an indication of how well the dropouts were doing, a chart showed 2% in humanities were receiving $ 20,000 and more annually while none of the Ph. D. ‘s with that background reached this figure. The Ph. D. ‘s shone in the $ 7,500 to $ 15,000 bracket with 78% at that level against 50% for the dropouts. This may also be an indication of the fact that top salaries in the academic fields, where Ph. D. ‘s tend to rise to the highest salaries, are still lagging behind other fields.
As to the possibility of getting dropouts back on campus, the outlook was glum. The main condition which would have to prevail for at least 25 % of the dropouts who might consider returning to graduate school would be to guarantee that they would retain their present level of income and in some cases their present job.
The author states that many educators feel that
[A] steps should be taken to get the dropouts back to campus.
the fropouts should return to a lower quality school to continue their study.
[C] the Ph. D. holder is generally a better adjusted person than the dropout.
[D] The high dropouts rate is largely attributable to the lack of stimulation on the part of faculty members.
Research has shown that
[A] Dropouts are substantially below Ph. D. ‘s in financial attainment.
the incentive factor is a minor one in regard to pursuing Ph. D. studies.
[C] The Ph. D. candidate is likely to change his field of specialization if he drops out.
[D] about one-third of those who start Ph. D. work do not complete the work to earn the degree.
Meeting foreign language requirements for the Ph. D.
[A] is the most frequent reason for dropping out.
is more difficult for the science candidate than for the humanities candidate.
[C] is an essential part of many Ph. D. programs.
[D] does not vary in difficulty among universities.
After reading the article, one would refrain from concluding that
[A] optimism reigns in regard to getting Ph. D. dropouts to return to their pursuit of the degree.
a Ph. D. dropout, by and large, does not have what it takes to learn the degree.
[C] colleges and universities employ a substantial number of Ph. D. dropouts.
[D] Ph. D. ‘s are not earning what they deserve in nonacademic positions.
It can be inferred that the high rate of dropouts lies in
[A] salary for Ph. D. too low.
academic requirement too high.
[C] salary for dropouts too high.
[D] 1000 positions.

Microwaves may be great at warming up food, but what about warming people?
Using microwaves to directly heat owners of a room would save much of the energy wasted by heating walls and furniture. And despite popular ideas about microwaves, this technique would be safe, according to Charles R. Burlier of the Microwave Research Center in Marlborough, New Hampshire. Low-power microwaves only penetrate (贯穿) the skin (low-power microwave penetration in a ham is about 0.2 inches, for example) and with no negative effects.
To test this idea, Buffler subjected himself to microwaves in a special room using a standard 500-watt, 2459 MHz magnetron (磁控管). He found that a person will start to feel warmth at about 20 kilowatts per square centimeter (mw. / sq. cm. ) ; a satisfactory feeling of warmth occurs between 35 and 50 mw. / sq. cm. By comparison, a person standing in noonday summer sun feels the amount of 85 mw. / sq. cm. And a frozen meat pie in your microwave oven receives about 1000 mw. / sq. cm.
In houses of the future, each room could be provided with its own magnetron, says Buffler. When you stepped into the living room, for example, a motion detector (运动感应器)would turn on the magnetron, filling the room with low-power microwaves. In the same way that a microwave oven heats up a hamburger, but not the plate it’s on, you would feel warmth from the microwaves without changing the temperature of your coffee table. (You could, however, make your favorite easy chair even more comfortable by treating it with a radiation-absorbing chemical.)
While it might be some time before homeowners are comfortable enough with the idea to set up whole-body microwave heaters in houses, Buffler says microwaves may attract livestock(家畜) farmers. Lambs that are born outdoors in winter, for example, are frequently lost to cold. Microwaves could warm the lambs safely and quickly.
Which of the following can tell the main idea of the passage?

A.A new heating system.
B.A new microwave oven.
C.A popular technique.
D.The magnetron.

According to Paragraph 2, which of the following does not describe the characteristics of a microwave heater?

A.It directly heats people in a room.
B.It heats walls and furniture in a room.
C.It is safe.
D.It saves energy.

The test conducted by Buffler shows that when a person feels comfortable warmth, he receives about ________________.

A.20 mw. / sq. cm. B.40 mw. / sq. cm.
C.60 mw. / sq. cm. D.85 mw. / sq. cm.

According to Paragraph 4, which of the following fills the room with low-power microwaves?

A.The magnetron.
B.The motion detector.
C.The microwave oven.
D.The radiation-absorbing chemical.

Which of the following statements about microwave heaters would Buffler most probably agree with?

A.Microwave heaters will soon be widely used by homeowners.
B.Microwave heaters sometimes make people feel uncomfortable.
C.Perhaps microwave heaters will be first used by livestock farmers, who wish to protect their lambs in winter.
D.Microwave heaters cannot be accepted by the public because they are somewhat unsafe.

People fell in love with Elizabeth Taylor in 1944, when she starred in National Velvet-the story of Velvet Brown, a young girl who wins first place in a famous horse race, At first, the producers of the movie told Taylor that she was too small to play the part of Velvet. However, they waited for her for a few months as she exercised and trained—and added three inches to her height in four months! Her acting in National Velvet is still considered the best by a child actress.
Elizabeth Taylor was born in London in 1932. Her parents, both Americans, had moved there for business reasons. When World War II started, the Taylors moved to Beverly Hills, California, and there Elizabeth started acting in movies. After her success as a child star, Taylor had no trouble moving into adult(成人)roles and won twice for Best Actress: Butterfield 8(1960) and Who’s Afraid of Virginia Woolf ? (1966)
Taylor’s fame(名声)and popularity gave her a lot of power with the movie industry, so she was able to demand very high pay for her movies. In 1963, she received $1 million for her part in Cleopatra—the highest pay received by any star up to that time.
Elizabeth Taylor is a legend (传奇人物) of our time. Like Velvet Brown in National Velvet, she has been lucky, she has beauty, fame and wealth. But she is also a hard worker. Taylor seldom acts in movies any more. Instead, she puts her time and efforts into her businesses, and into helping others — several years ago, she founded an organization that has raised more than $40 million for research and education.
The producers didn’t let Taylor play the part of Velvet at first because they thought she ____.

A.was small in size B.was too young
C.did not play well enough D.did not show much interest

What Elizabeth Taylor and Velvet Brown had in common was that they were both _____.

A.popular all their lives B.famous actresses
C.suecessful when very young D.rich and kind-hearted

Taylor became Best Actress at the age of .

A.12 B.28 C.31 D.34

In her later life , Elizabeth Taylor devoted herself to .

A.doing business and helping others B.turning herself into a legend
C.collecting money for the poor D.going about research and education work

Adult butterflies use their senses of sight, touch, hearing, smell, and taste to survive in the world, find food and mates, lay eggs in an appropriate place, migrate, and avoid hungry predators.
Sight
Butterflies have large, compound (multifaceted) eyes, which allow them to see in all directions without turning their heads. Like most insects, butterflies are very nearsighted, so they are more attracted to a large stand of flowers rather than individual plants. Butterflies do not "see" colors such as red, green, and yellow, but sense polarized(偏振的) light, which indicates the direction the sun is shining, as well as ultraviolet light, which is present on many flowers and guides butterflies to nectar (花蜜)sources.
Smell
Butterflies have a very well-developed sense of smell, but it's not in their nose (since they don't have one). Sense receptors located in their antennae, feet, and many other parts of the body help butterflies find food (usually flower nectar), and mates (the female smells the male's pheromones).
Taste
Butterfly's feet have sense organs that can taste the sugar in nectar, letting the butterfly know if something is good to eat or not. Some females also taste host plants in order to find appropriate places to lay their eggs. Adult butterflies and moths feed using a proboscis, a long, coiled tube. Butterflies force blood into the tube to straighten it out, allowing them to feed. Butterflies get all their food from this tube.
Hearing
Butterflies don't have ears. Instead they "hear" sounds through their wings by sensing changes in sound vibrations.
Butterflies may possess senses we don't even know about yet because their anatomy is very different than ours, and therefore difficult to understand when perceived through our own human senses.
From the passage we can know that butterflies can see_____

A.thing behind them B.thing in the distance
C.most bright colors D.flower nectar from a distance

Butterflies can easily find food resources by using their______.

A.sense organs of sight and smell B.sense organs of sight and taste
C.sense organs of smell and hearing D.sense organs of smell and taste

How do butterflies feed themselves?

A.by using their feet B.by using a tube.
C.by using sense receptors D.by using their wings.

What is the passage mainly about?

A.The food sources of butterflies. B.The habits of butterflies.
C.The unusual body of butterflies. D.the sense of butterflies.

In the long discussion of water on the Moon, a new study contradicts(与……相矛盾)) some recent reports that say the Moon had water at the time of its formation. A group of researchers reported in the journal Science that when the Moon was created, some 4.5 billion years ago, there was not much hydrogen(氢气) on it, and therefore no water.
The researchers surveyed and evaluated this by analyzing chlorine isotopes(氯同位素) found in lunar rock samples from Apollo missions. The range of chlorine isotopes in lunar samples was 25 times that found in samples from Earth.
If the Moon had significant levels of hydrogen, as Earth did, this range would have been far less, said Zachary D Sharp, a scientist in the Department of Earth and Planetary Sciences at the University of new Mexico and the study’s lead authour.
The chlorine would have stuck together with hydrogen, forming compounds like hydrogen chloride, and escaped from the Moon’s surface, he said. The abundance of chlorine indicates a lack of hydrogen and water.
“ The amount of water on the Moon was too low for life to possibly have existed there,” he said.
Most scientists believe the Moon was formed when a large object stuck Earth, breaking off a chunk(a vast piece) that has since orbited Earth.
On Earth, goes one theory, water was released as steam form molten basalts(玄武岩) over time, eventually forming bodies of water.
“An understading of whether the Moon was dry or wet will help us understand how water appeared on Earth,” Dr Sharp said.
A new study indicates that _____ on the moorn.

A.there is plenty of water B.water is unlikely to exist
C.water existed in the past D.there is a little water now

The author would like to tell us ______ through the sixth paragraph.

A.why there is no water on the Moon B.how the Moon was formed
C.when the Earth struck the Moon D.where the Moon orbited

Which is NOT true according to the passage?
A. Zachary D. Sharp, a scientist of New Mexico was in charge of the new study.
B. Chlorine isotopes in lunar samples are 25 time larger than those on the Earth.
C. The more aboundant chloride, the shorter hydrogen and water.
D. The new study is benificial to understand how water appeared on Earth.
What can we learn from the passage?

A.There is enough water on the Earth.
B.Hydrogen chloride easily escaped from the Moon’s surface.
C.The Earth had significant levels of hydrogen.
D.Water on the Earth is directly from molten basalts.

They leap from helicopters or speeding boats, bringing aid to swimmers who get into trouble off Italy’s popular beaches.
For these dog lifeguards, the doggie paddle (狗刨式游法)does just fine.
These “lifedogs” tow a buoy(救生衣) that victims can grab, or a raft they can sit on to be towed back to shore, and unlike their human counterparts(与对方地位相当的人), they can easily jump from helicopters and speeding boats to reach swimmers in trouble.
With millions flocking(人群) to Italy’s crowded beaches each summer, the Italian Coast Guard says it rescues about 3,000 people every year — and their dog helpers are credited with saving several lives.
It takes three years for the canines to reach expert rescue status, and currently 300 dogs are fully trained for duty, said Roberto Gasbarri, who co-ordinates the Italian School of Canine Lifeguards program at a centre outside of Rome in the seaside town of Civitavecchia.
“Dogs are useful in containing the physical fatigue(疲劳) of the lifeguard, to increase the speed at which casualties(遇难者) are retrieved(找到并衔回), to increase the security of both the casualty and of the lifeguard,” Gasbarri said.
The Civitavecchia centre is one of a dozen around the country for the school founded more than 20 years ago in the northern province of Bergamo by Ferruccio Pilenga, whose first trainee was his own Newfoundland.
The school will train any breed(品种), as long as they weigh at least 30 kilograms, but Labradors, Newfoundlands and golden retrievers are most commonly used because of their natural instinct for swimming. Each dog works in tandem with(同 ……合作) a human lifeguard, who also acts as the animal’s trainer.
Which of the following can act as the best title fo the passage?

A.Dogs to the Rescue B.Dogs Are Good at Doggie Paddle
C.The Wonderful Performance of Dogs D.Dogs: Our Loyal Friends

What advantage do these life-dogs have over human lifeguards in a rescue?

A.Dog can swim very fast B.Dogs can finish rescue work with ease.
C.Dogs can finish the great work free of charge. D.Dogs can easily be trained

Which of the following is TRUE about the Civitavecchia center according to the text?

A.Any breed can be trained there.
B.The ones who have the gift for swimming are welcomed.
C.After a better training, the dogs can work alone.
D.It is the only place for training dog lifeguards in the school.

What does the writer want to tell us in the 4th paragraph?

A.Without the dog lifeguards, 3,000 people would lose their lives every year.
B.The buautiful beaches attract millions of people every year.
C.Dog lifeguards play an important part in a rescue.
D.Italy is a famous place of interest.
